Project 2

1) Open dlubal software and click new

2) Edit the name and description

3) Click tick mark for both form finding and cutting pattern

4) Click Ok

Step 2:

1) Click new nodes

2) Place the nodes as per the question

3) Click new line option and draw the lines based on the nodes placed

Step 3:

1) Double click the line

2) Assign the members in the line using members option

Step 4:

1) Choose the member type as cable

2) Assign the proper material from the libraries

3) Click ok

Step 5:

1) Click New nodal support option

2) Choose rigid or hinged from the option

Step 6:

1) Place the nodes on the corner of the members

Step 7:

1) Click Insert option and choose surface

2) Choose the area which wants to be cover as surface

3) Assign the member type as quadrangle and membrane orthotropic

Step 9:

1) Input the Nx an Ny value of form finding as 1 kn/m

Step 10:

1) Assign the load cases from the bottom drop downlist

2) Set the load of selfweight, imposed and wind (if necessary)

Step 11:

1) Similarly assign the load and result combination of the applied load cases

Step 12:

1) From the display option choose RF limits

2) Set the limits and its parameters

Step 13:

1) Apply the load cases on the model

Step 14:

1) Click loads and apply surface loads on the model

2) put negative load in the imposed one.

Step 15:

1) Click calculate option

2) Set the mesh settings

3) Generate the mesh

Step 16:

1) Click calculate all to run the analysis

Step 17:

1) Results of the analysis has been obtained

Step 18:

1) Check the limit checks by surface using RF limits option

Step 19:

1) Click tools and click generate cutting patterns

2) Double click the dotted one

Step 20:

1) Set the warp as 1 and weft as 3% in compensation

Step 21:

1) Similarly 0.1 as welding line and 0.2 as border line in allowance

2) Click calculate

Result :

Therefore cutting patter values has been obtained successfully.
